The 1973 “Secrets of a Call Girl” must be the ultimate Edwige Fenech movie. Not necessarily the best one, just the one that shows her from the most angles. In this sense it’s a bit like Antonio Pietrangeli’s 1965 “I Knew Her Well,” starring Stefania Sandrelli – a riff on the various aspects of a movie beauty. (The Italians, eh? When exploiting a female type they leave nothing on the table. Is it any wonder they’re the unofficial mascots of the Madonna-whore complex?) Edwige plays a cashier who becomes attached to a thuggish mafioso. Naturally, he wallops on her, and of course she keeps coming back for more. But when he involves her in his criminal schemes things turn ugly — he starts pimping her out to his marks. (There are more than a few nods to Hitchcock’s “Notorious,” in which Cary Grant’s shepherding of Ingrid Bergman acquires overtones of forced prostitution.) This early section is in the grotty style of the Italian police film, complete with a chugging score composed by Luciano Michelini. But around the movie’s middle point it morphs into something akin to a ’40s woman’s picture, with Edwige occupying the Joan Crawford role. She moves out of Milan, has a child, and begins nursing a romance with a doctor who’s like a purified version of her still-out-there-somewhere former beau. Throughout the picture Edwige looks stunning; she’s got a face that could melt the heart of a snowman. She gets to act a little, too. Directed by Giuliano Carnimeo, who helmed one of Edwige’s most memorable giallo outings, the 1972 “The Case of the Bloody Iris.” Richard Conte turns up for about five seconds.
